In the enrobing machine of Bakon Food Equipment, the MX-20-R progressing cavity pump of KNOLL Maschinenbau ensures reliable pumping of sensitive media such as chocolate and fondant. Worldwide many customers in the baked goods industry use machines from Bakon Food Equipment (headquartered in Goes, Holland) to spray or coat cakes, pralines and sweets, to glaze, plate, and cut them. Bakon’s product offerings also include complete systems, such as the “cake line”, which can plate, glaze, and cut both round and square cakes at one go.
Bakon uses the progressing cavity pump MX of KNOLL Maschinenbau to pump fondant and chocolate in a liquid state for many years. To hold the product at a constant temperature, KNOLL applies a MX 20-R-40/10 with double jacket for heating the pump unit. The main advantages of the MX are its gentle pumping characteristics of abrasive media. The feeding screw in the hopper housing supports a continuously pumping of chocolate and fondant with low pulsation.
The many advantages of the EvenWall®-technology of the stator offer the customer e.g. a high pressure stability, long lifetime and a production by low consumption. Similarly, the compact assembly length makes concessions to the small space in the enrobing machine of Bakon and enables an easy integration of the pump into the system of the machine. Get more information about the use of the MX in the baked goods industry and visit us at the IBA in Munich, from 12. – 17. September 2015 in hall A5, booth 311 – we look forward to your visit!

Apart from numerous applications in which hygienic aspects of the KNOLL progressing cavity pump MX play a central role, the MX can also used in an extremely beneficial manner in KNOLL’s core business. One new application is the use of the MX in KNOLL‘s in-house Test Centre. Here, KNOLL tests the operability of all cooling lubricants and conveying systems.

For the wet test, the tank on the installation to be tested is initially filled with cooling lubricant from a central collection tank. All pumps, valves and other installation components are set to meet customer-specific requirements. This means that the wet testing procedure takes place largely under real conditions. If the installation test is successful, the cooling lubricant is drawn off again by a vacuum suction unit into a vacuum tank. Thanks to its excellent suction performance, the MX is able to draw off the cooling lubricant continuously from the vacuum tank even at a negative pressure of -0.7 bar and to convey it into the sludge tank of the central collection tank.

Small dirt particles, e.g. welding debris, which may have entered the installation during the production process, are no problem at all to the MX. From the sludge tank, the cooling lubricant is then routed to the attached KNOLL filter for thorough processing. When the cooling lubricant has been filtered, the circuit closes and the purified cooling lubricant is available once again in the central collection tank for a further wet test.

Without the use of the MX, the vacuum suction unit would require a considerably higher tank capacity. The vacuum would also have to reduced regularly to ensure that emptying with a conventional pump is possible.

Confectionary – who can resist the sweet temptation? On average, Germans eat 32 kg of sweets in a variety of forms every year. Hard candies are particularly popular, coming as they do in many different flavours.

Crucial factors for the customer are the hygienic design of the MX and its excellent cleanability. As with many plant constructors, the MX scores highly for its compact overall length which allows the pump to be integrated into the overall system in a space-saving way. The high dosing accuracy of the MX enables Hänsel Processing to fill exactly portioned batches of hard candy mass.

For this application, KNOLL uses a heated stainless steel double jacket for the MX as standard. This allows media such as toffee, fondant or jelly mass to be kept at a constant temperature and, thus, to be conveyed easily and gently. The uniform elastomer wall thickness of the EvenWall® stator provides good, even heat transfer between the double jacket and the medium. The uniform thermal expansion of the stator elastomer has a very positive effect on its useful life and, thus, on the productivity of the overall system.

Do you also work in the confectionary industry, and have we managed to arouse your interest in our “sugar worm”?If so, please give us a call. It’s a safe bet that you’ll find a suitable KNOLL MX solution for your application in our product range.

The MX progressing cavity pump by KNOLL offers product-conserving delivery, ease of servicing and virtually pocket-free design, as well as a string of other advantages.

KNOLL uses a bearing block in each of its progressing cavity pumps from the compact MX10 version to the XXL-sized MX100 version. This unique feature clearly sets KNOLL apart from its competitors.
By using a bearing block, we can supply the pump without a drive unit. The advantage here is that the customer receives a ready-to-use standby pump with no need for laborious shaft sealing unit assembly.

Another advantage is that the axial forces are absorbed by the bearing block and do not have to be factored into the design of the geared motor. This allows the use of smaller and more cost-efficient drive units.
A stainless steel-bearing block is standard on the MX10 and MX20 models, which means that KNOLL is able to supply these pumps entirely made from stainless steel. Used in combination with a stainless steel geared motor, the MX is the perfect solution for hygiene environments and similar applications because it can be cleaned easily and quickly.

Discover for yourself the advantages and performance of our progressing cavity pump MX and contact our sales representative. We will be happy to sit down with you and design a custom solution tailored to your application needs.

The RONDO FOOD company, which specialises in snack products for cats and dogs, has been using MX progressing cavity pumps by KNOLL for a number of years now with highly satisfactory results. RONDO FOOD has made an international name for itself as a supplier of private label products to commercial and industrial enterprises in the European, US and Asian markets.

When it comes to the production of pet snacks, RONDO FOOD places great emphasis on fast and hygienic processing of fresh meat. The meat is made into a slurry with a viscosity of between 1,000 and 3,000 mPas. This slurry contains chunks of meat 1.5 x 0.5 mm in size. Gentle product delivery is very important because these chunks must not be destroyed. This unique feature of the MX progressing cavity pump by KNOLL is a key criterion for RONDO FOOD. Today, nearly 50 MX progressing cavity pumps are used by RONDO FOOD at various production sites so as to ensure maximum customer satisfaction.

The MX also has other advantages in addition to gentle product delivery: the proven EvenWall® technology of the high-compression stator allows pressures of up to 10 bar per pressure cycle, which saves space and, most importantly, cost. That means KNOLL can also supply small and cost-effective MX progressing cavity pumps for high-pressure applications. Due to the stringent hygiene requirements which apply in the pet food industry, cleaning and maintenance are important to RONDO FOOD. In this department, the MX scores highly with its service-friendly design. Thanks to its modular principle, it can be disassembled easily and quickly. The MX progressing cavity pump by KNOLL is at home in the hygiene sector and can be easily cleaned and sterilised using CIP and SIP methods by virtue of its virtually pocket-free design. Another plus-point is the low part diversity – which greatly simplifies both maintenance and stocking of parts by the customer. Because the pumps in the MX series differ from one another only in terms of their pump unit, which comes in nine different sizes, the wear parts of, say, the shaft seal and universal joint are identical and can be used flexibly.

The MX progressing cavity pump from KNOLL is used in many different areas, from the food and beverage industry to pharmaceuticals to the chemical industry. This pump also stands the test in extreme cases. This has been proven at Europe’s leading manufacturer of building shells, interior fittings, and insulation technology. Here, the MX is incorporated into the process of reclaiming fibrous plasterboard. It withstands temperatures of 140 ° C and an extremely abrasive fluid.

Waste and remains of the plasterboard panels are relegated to a viscous suspension of approx. 500 mPas. Using the MX, this fluid is pumped back into a reactor before it is processed into new fibrous plasterboard. A challenge of this use is the high temperature of the fluid, 140 °C. Thanks to its special design, the MX performs well: the EvenWall® technology of the KNOLL stator guarantees even pressing even at high temperatures. This improves the durability of the stator considerably. Another challenge of the fluid is its abrasive character. The plaster suspension contains 10 – 15 µm particles with a concentration of 32 – 50 %. The MX also has the solution for this: a stator of wear-proof special elastomer for high temperatures as well as a specially-coated rotor, which also demonstrates wear-proof qualities despite the extremely abrasive fluid.

An additional benefit of the KNOLL MX progressing cavity pump is the even flow speed in the suction housing, which prevents sedimentation and thus the settling of the fluid. This is the result of the even diameter of the cardan joint and the pump’s design, which keeps the clearance volume low. Therefore, no fluid accumulations form on the joint or on the housing wall.

Rotary piston pumps were used for this process in the past, however without any success. After just a few weeks, the pumps had to be replaced due to wear. The MX progressing cavity pump from KNOLL has been used for six months already and shows no traces of wear.
